Chapter 34 ("Don't Know") of Rick Hanson's book Just One Thing explores the vital importance of space, of emptiness, of leaving room to grow and learn, of holding back and delaying the tendency to reach a conclusion. Among the exercises he suggests trying are to wait for others to finish speaking in conversation, to observe objects without labeling them, to let go of the urge to grasp at "the answer", and continually to question assumptions and authorities. Hanson concludes with a benediction:

"May you know less after this practice of not-knowing than when you began."
